	* app/display/gimpdisplay.[ch]: removed gdisp->scale,
	gdisp->dot_for_dot, the scaling marcos and the
	gdisplay_[un]transform[_f]() functions.

	* app/display/gimpdisplayshell.[ch]: added them here. Named the
	transform functions gimp_display_shell_[un]transform_xy[_f]().

	Made the gimp_display_shell_[un]transform_coords() functions copy
	all values of the GimpCoords struct, not just x and y.

	* app/display/gimpstatusbar.[ch]: keep a pointer to
	GimpDisplayShell, not GimpDisplay.

	* app/gui/layers-commands.c: if(gimage->selection_mask) is always
	TRUE, use if(!gimp_image_mask_is_empty(gimage)) instead.

	* app/tools/gimpfuzzyselecttool.[ch]: moved global variables
	to the object struct.
